Engineering Technician Jobs

About The Position

Requirements

• Associate degree or bachelor’s degree in geology, materials science, chemistry, civil engineering, or a related field preferred; relevant laboratory experience will be considered.
• Knowledge of mineralogy, concrete technology, or construction materials is a plus.
• Experience working in a laboratory setting, handling petrographic or construction materials, is highly desirable.
• Familiarity with ASTM standards related to petrography and construction materials testing is beneficial.
• Basic computer skills, including Microsoft Office Suite, laboratory data management systems, and digital microscopy software.
• Strong attention to detail, ability to follow technical procedures, and interest in forensic material science.

Nice To Haves

• Experience with petrographic or optical microscopy is a plus.
• Knowledge of cement chemistry, aggregate durability, and concrete deterioration mechanisms.
• Hands-on experience with sample preparation techniques, including cutting, polishing, and staining of concrete specimens.
• Ability to interpret macroscopic and microscopic observations related to material distress.
• Strong verbal and written communication skills for technical documentation and reporting.
• Interest in career progression within the Petrography Job Family, advancing towards Petrographer and Senior Petrographer roles.

Responsibilities

• Prepare, process, and handle samples (e.g., concrete, aggregate, mortar, cementitious materials) for microscopic and chemical analysis in compliance with ASTM, AASHTO, and AET standards.
• Cut, grind, polish, and create thin sections of concrete and rock specimens using precision saws, lapping machines, and polishing wheels.
• Assist in staining and dye penetration techniques for identifying cement paste, aggregate, and reaction products under fluorescence and polarized light microscopy.
• Conduct basic petrographic examinations using stereo microscopes, reflected light, and transmitted light microscopy to classify materials based on texture, mineral composition, and degradation characteristics.
• Conduct fundamental petrographic analyses to classify materials, assess aggregate reactivity, and evaluate concrete distress using ASTM C295, C856, and C457 standards.
• Assist in chemical and durability testing, such as sulfate soundness, chloride content analysis, and air-void system evaluations, to support petrographic findings.
• Accurately log and document sample data, ensuring proper traceability and compliance with industry standards and laboratory protocols.
• Collaborate with Petrographers and Senior Petrographers in the assessment of failed concrete structures, asphalt pavements, and construction aggregates to determine material deficiencies.
• Support forensic investigations by helping collect field samples and preparing visual macro/microphotographs of material defects.
• Learn and assist in interpreting petrographic data and drafting preliminary laboratory summaries for internal review.
• Maintain clean, organized, and calibrated laboratory equipment, ensuring compliance with quality control standards and AET safety protocols.
• Assist in reviewing laboratory procedures to ensure that all work aligns with industry best practices and client specifications.
• Follow established safety protocols, including handling chemicals, wearing PPE, and properly disposing of laboratory waste.
